Summary of Activity and Data Gathered: Overall data quality is excellent, with good resolution and penetration. Some areas of rough topography obscured the underlying structure. Records show slumping and other mass sediment movement occurred at several places on the continental slope adjacent to Georges Bank. Slumping occurs in scales that range from small to large and in styles that range from simple downslope creep to major dislocation. Most slump bodies are found near the base of slope with marked erosional truncations above. Records from the edge of the continental shelf show numerous buried channels of varying size and configuration. Inside the 60 m isobath extensive fields of large sand waves are present. 3.5 kHz: 218 km; Minisparker: 2669 km; Airgun: 2142 km.
